     Navigant Consulting, Inc. (NYSE:NCI), an international consulting firm
providing dispute, investigative, operational, risk management and financial
advisory solutions to legal counsel, government agencies and companies
experiencing regulatory or structural challenges, today announced financial
results for the 2006 second quarter.
     "Our solid second quarter results completed a strong first half of 2006,
which included excellent performance from our financial, insurance and
international sectors, as well as our forensic accounting and investigation
services," stated William M. Goodyear, Chairman and CEO. "In particular, our
forensic accounting expertise and recognized professionals, combined with our
strong brand, have positioned us as a leading firm to assist companies in
addressing back-dating stock option concerns. Overall, we are well positioned to
sustain our current growth throughout 2006 and achieve our previously-stated
revenue and earnings goals for the year."

     Second Quarter 2006 Financial Results

     Revenues for the second quarter of 2006 were $165.0 million, an 18 percent
increase compared to second quarter 2005 revenues of $139.5 million, and a
slight decrease from first quarter 2006 revenues of $166.3 million. EBITDA in
the second quarter of 2006 was $31.0 million, an increase of 17 percent from
$26.5 million for the second quarter of 2005, and up slightly from first quarter
2006 EBITDA of $30.7 million.
     EBITDA as a percentage of revenues before reimbursements remained
consistent with the first quarter of 2006 at 21 percent, and was down slightly
compared to 22 percent during the second quarter of 2005. Net income per diluted
share was $0.26 in the second quarter of 2006, an 8 percent increase compared to
$0.24 per share in the comparable period in 2005, and consistent with the first
quarter of 2006.
     "Net income per diluted share during the second quarter of 2006 was
impacted by higher amortization, depreciation and interest expenses, principally
due to the effects of our acquisition of London-based Precept in late March. Our
UK and other international operations have significantly benefited from this
transaction, and we are very pleased with the results of our foreign operations
despite this short-term impact to non-operating expenses," stated Mr. Goodyear.
"In addition, shares used in computing net income per diluted share increased,
quarter over quarter in 2006, by more than 1.1 million shares, principally due
to the Precept acquisition and other previous transactions."

     Six-Month Financial Results

     Revenues for the six months ended June 30, 2006 were $331.2 million, a 21
percent increase compared to 2005 six-month revenues of $274.1 million. EBITDA
for the six-month period of 2006 was $61.7 million, up 18 percent from $52.2
million for the comparable 2005 period. EPS for the 2006 six months was $0.51
per share, compared to $0.49 per share for the same period in 2005.
     "In addition to the expansion of our international dispute and
investigations offerings, we are experiencing strong demand for our financial,
operational and risk management solutions, particularly in the financial
services and healthcare industries," stated Julie M. Howard, President and Chief
Operating Officer. "Recent engagements have focused on reengineering financial
systems and accounting processes in support of restatements, counseling clients
in setting up appropriate processes to comply with regulatory requirements, and
reviewing internal audit and other risk management functions."

     Business Metrics

     Average billable full time equivalent (FTE) consultant headcount for the
second quarter was 1,729, as compared to 1,733 in the first quarter, and 1,545
in the second quarter of 2005. FTE billable consultants on June 30, 2006 were
1,732, down from 1,787 at the end of the first quarter 2006, and up from 1,557
at June 30, 2005. Company-wide consultant utilization in the second quarter was
70 percent, compared to 71 percent in the first quarter of 2006 and 69 percent
in the second quarter of 2005.
     Annualized revenue per consultant in the second quarter of 2006 was
$376,000, compared to $384,000 in the first quarter of 2006. Annualized
attrition was 20 percent during the second quarter of 2006, up from 18 percent
during the first quarter. Days sales outstanding as of June 30, 2006 were 83
days, compared to 81 days at the end of the 2005 second quarter. The Company
ended the second quarter with $75.7 million in bank borrowings under its $175
million unsecured, multi-bank credit facility.
     "Voluntary consultant attrition at the junior consulting levels trended
seasonally upward in the second quarter as a result of increased interest in
graduate program opportunities, as well as expanding industry opportunities, but
such attrition remains constant in the single digits for our senior
professionals, " stated Ms. Howard. "We are looking forward to welcoming a
substantial complement of new campus hires over the next several months."
